A novel receiver circuit for Chirp UWB communication system has been designed and realized by utilizing the pulse compression characteristics of linear frequency modulation (Chirp) signals in this paper. First of all, two identical Chirp UWB signals are compressed with two SAW dispersive delay lines (SAWDDL) with different slopes. Then the original symbols are recovered by envelope detector, shaping, A/D sampling as well as the digital processing modules. It can be seen from the simulation results that the receiver has obviously high reliability. In addition, the hardware circuit can simply perform debugging and therefore it enables the production to be promoted with larger volume.
